Parameters:

parameter - the method parameter to resolve. This parameter must have previously been passed to HandlerMethodArgumentResolver.supportsParameter(org.springframework.core.MethodParameter) which must have returned true.

mavContainer - the ModelAndViewContainer for the current request

request - the current request

binderFactory - a factory for creating WebDataBinder instances

Returns:

the resolved argument value, or null

Throws:
